I'n all whom it may concern .i

llc it known that l, Romair H. SCROGGINS,

` residing at Fairfax, in the county of Fairfax and State .of Virginia, have invented a new and Improved Street-Sweeping Machine, of which the following is a specification.

This invention relates to improvements in that class of motor driven "street sweeping machines in which the sweepings are conveyed, by suitable elevating devices, into a discharge Athat empties into a receiver carried by or movable with the sweeping inachine or carriage.

My invention primarily has for its object to provide an improved construction of machine of `the general type stated, in which, the coperating parts are so designed and combined, whereby a compact arrangement' of the mechanism is'provided for, which can' be economically constructed and in which thecontrolling devices for the several independently 'actuated means can be readily .manipulatedby the driver and in such a manner that he can take care ofthe actuating mechanism wit-houtv interfering with` a quick and positive-action of throwing the motive power and in consequence all. the

working partsout of. gear, and for lifting eitherv the main 0r supplemental rotary brushes out of contact withthe surface while underroth-ry action.

`With other objects in View that will hereinafter appear, my invention consists in the improved street sweeping machine, em-

bodying the peculiar'const-ruction and novel better'illustrate the correlation thereof. Fig.

3, is a vertical, longitudinal section ofthe same, taken practically onthe line 'ti-3 on Fig. 2. Fig.`4,is a detail section of the cross conveyer or auger hereinafter specifically referred to. Fig. 5, isan end elevation. Figli, is a detail view of a modified form of elevating lifting blade or bucket.

In the practical application of my invention, the power and actuating devices are arms with the rotary brush,

Ycan be readily raised,- or lo mounted on a suitably constructed vehicle or wagon framing, that includes the front and hind sets of wheels 1-2 and the bed or platform 3, from which extendstandards 114-4 60 to, support a decking or covering 4 mounted over the motor mechanism and the operators seat.

' 5 desi ates a motor -of any approved construction, vmounted on the forward end of theplatform and which is covered from the dust or dirt as it is being swept up, by a sheet metal housing 50, and to assist in driving the dust forwardly and to protect the operator therefrom, the motor is coupled with. and drives 'a fan 51 that operates just inside of the slatted front wall 52 of the housing as is clearly shown in Fig. 3, by reference to which it will bealso observed the motor has its fly .or power wheel 54 75 formed with a cone clutch rim 54 for coactL ing with a cone clutch disk 60 slidable and keyedk on the driven or power transmission shaft 6. The clutch disk 60 is controlled by a lever 7 pivotally mounted adjacent the 30 operators seat 8, the said-.lever having coniiectionwith the annularly grooved clutch collar 54h through the link 71 and the, straddle head 72 that seats inthe groove of the collar 54", it being obviou s fseefFig. 3, that 95A by adjusting the lever 'Z to trie position shown, the shaft`6 will be in gear with and driven-by the motor and thus transmit the` power for actuating all of the'` active or workingj-parts of the sweeper', but when 90 shifted ack in the direction of arrow a: the motor and the driven shaft will be disconnected. 7

9 designates the main rotary sweeping brush, the shaft of which is journaled in the forwardly and downwardly extended ends 10 of a pair of oppositely disposed and parallel side'l arms 11 that are t-iltably' l supported on a cross'shaft 12 -(presently again referred to) and 'the rear' ends of 100 which are longitudinally slotted as at 11H-11W to receive -the "studs 13a .on the crankslB fixedly connected to a rock shaft 14 that extends transversely of and issuitably mounted o n the platform, itlhaving a 1'05 fixed connection with a lever 15 that extends upwardly for being 'conveniently 4Vhandled by the operator, whereby, -'by a l, prop r .e shift-ing of the said lever, the ftiltabllside with rthe. supporting voke trame of thev smaller rotary brush.

The smaller or siipplemental brush. in ii'rvl complete machine structure. islocated at. one or both edges' of the vl'ront end of the machine. and is diagonally positioned and forwardly projected with respect to the -said end,'.as best shown in Fig. 2, such arrangement of the supplemental brush making it' possible .to direct the same to aiidprojeet the same into corners and suclrl'ilaces-where it would lie-'impossible Ato pointv the` supplementaldirush were it positioned infront ofk or at the side ot' the main vhriisli mechanism',- in planes parallel therewith. 'll-ie smaller 3-l brush lil-has its..journals 195* mounted lir'i'i `thevpendeut ends of a yok'ef frame `tltl'fthat includes a rearwardly [extended horizontal bifurcated portio11. 20`. seei Fig. 2,7m wlich 4the adjacent. end of the lower-shaft. 21 for the'y ele yatorpresently again referred to, is

Referring again to Fig. 3 it will he seen.

the main brush is located in a housing 26 the s1de walls vof which have segment slots 26 to permit the rise. and fall of the main brush, and each journal end of the main brush carries a chain gear 27 around which take the endlesschaiu belts QS that also pass over drive chain. gears lt) --29 on a cross shaft 12 mounted' in journal boxes on the under side of .side lieanis ottlic plattoi'ni, the said shaft. 1; receiving motion through a chain helt- 3l that engages a chain wheel 32 on the shaftlQ and a'like wheel 38 that is loosely mounted on the i'iotor driven shaft (l and having a clutch face 3l for coactiiig with a. sliding clutch 35 ondhesaid driven shaft, with which connects a hell crank llt', controlled hy a lever 37adjacentthe driver`s 'sc-at. it. being apparent the latter clutch mechanism utilized for controlling the. starting a-iid stopping ol the rotary sweeper Y .ind the elevator mechanism that' coacts therewith. l

Coperatmg with the main driven-shaft 1s a second driving shaft 3l that meshes over a belt pi'illev 8 with the main shaft, throughjthegears 35K-Sti and the said shaft-341,. carries chain gears :lli around which takei'tliritifing chain hehs BTC-3T' that pass aroundd'argechain wheels' on the axles ot' hoth/o'f the hind wheels of the truck, as is clearly shown in ["igs. l aud 3. f Y

.At the lower or take-up end of the main sweeper roll is pivotallvI suspended a dust or dirt Vpan Jfl,'t.he opposite ends4lof which st raddle the correspomling ends ofthe brush and serve to positively collect' t-liedirt swept up and to direct it in auf upwardly and for wardlv direction.

The conveyer'SB-luis its receiving endloeated just under tlie'discharge end of the auger trough-and its conveyer belt S9 is driven by the chain pulley tl() on one end of the' shaft lli). on which.the lower beltl pulley 93 of the conveyer S8 is mounted, and with which engages a. drive. chain Sil .that passes over a chain wheel 95 on the auger shaft and over a drive wheel 9C.

In Fig. 2 it will be vnoticed I have shown two oppositely-disposed bag hangers, each of which consists of a endent arm 101, one of which is pivotally ung on each side of the throat piece and has a crank 102 at the upper end vconnected through pendent rods 103 with a treadle lever 104 lmounted on a sub-platform 105 pendent `'from the rear end of the main platform. At the lower end reach arm 101 has a substantially semicircular rim 105a formed with hanger pins 106 and the treadle'connects with the Vsaid arms in such manner that the mouth of the bag or` receiver X can b e readily slipped up over the two rims 105 and when thus tted, by pressing down on the foot lever the rims 105 are opened out to cause their rims to spread and the mouth of the bag to securely hold it in place,

' a hand lever 106a being used in connection withv` a curved ycut-olf 107 for closing the discharge from the bag receiver while taking oi or putting on the bags or holders.

From the. foregoing,taken in connection with the accompanying drawings, it is be lieved the complete structure, thev manner in which my machine operates and the advantages thereof will bereadily apparent to those skilled in the art to which my invention relates.

-It will be understood that slight changes in the details of construction shown, and modifications4 thereof may be made without departing from my in the appended c aims. I `or example, instead of utilizing the conventional type of lift slats on the main elevator, bucket-like slats or lift ortions arranged as shown in Fig. 5 may e used and this form is especially advantageous for use on streets where the soil or sweepings are mucky or wet.

The main points of advantage of my invention are the arrangement of the controlling lever mechanism so the driver can easily invention expressed adjust and control the entire operation of adjusting the parts or .setting .them in and out of operation. Again, by arranging the elevator at the front to extend the full width of the machine and housing the elevator as shown, the bulk of the dust from thesweepings is carried olf with the take-off or longitudinal conveyer while the blast fan arrangement tends to positively drive forwardly what other dust comes up from the brushes and thus protect the driver. Placing-the motor mechanism as shown, balances the machine and permits f an inexpensive and easilyl controlled arrangement of power transmission gearing being utilized.

While but one supplemental brush is shown and described, it is obvious that a supplemental brush may be lused for each corner of the sweeping end of the machine.

A water tank, indicated by m on the drawings, is mounted on the truck or motor wagon and extends lengthwise thereof, with which, in practice, sprinkling means of any approved type may be connected.

Having thus described my invention, what I claim is:

1. In a street sweeping machine,A a main dirt gathering land elevating mechanism, the said Imechanism including a lower elevator shaft, and means for operating the sameya supplemental dirt gathering means including a supporting device pivoted on the said elevator shaft, and power transmission connectin said supplemental gathering means and tie said lower shaft.

2. In a street sweeping machine, a main dirt gathering and lelevating mechanism, the said mechanism including a lower elevator shaft, and means for operating the same; a supplemental dirt gathering means including a supporting device pivoted on the said elevator shaft, and power transmission connecting said supplemental gathering means and the said lower shaft, and means for elevating the said support and the vsupplemental gathering device carried ,thereby wit-hout disconnecting the power transmission connections.
